# Take arrays
n = int(input("Enter array size: "))
arr1 = []
for i in range(n):
    arr1.append(int(input(f"Array1 element {i+1}: ")))

arr2 = []
for i in range(n):
    arr2.append(int(input(f"Array2 element {i+1}: ")))

# Element-wise product
product_arr = []
for i in range(n):
    product_arr.append(arr1[i] * arr2[i])

print(f"Product array: {product_arr}")

Output

Enter array size: 3
Array1 element 1: 2
Array1 element 2: 3
Array1 element 3: 4
Array2 element 1: 5
Array2 element 2: 6
Array2 element 3: 7
Product array: [10, 18, 28]

Multiply corresponding elements.

Key Concepts:

Arrays must be same size
Multiply arr1[i] * arr2[i]
Create new array
